Electrolytic capacitor and multi-anodic attachment
First Claim
1. A method forming an anode stack for a cylindrical capacitor, the method comprising:
- providing two or more conductive ribbons, each having an insulative coating; and
winding portions of the conductive ribbons around an axis with sufficient force to establish electrical contact of two or more of the conductive ribbons through their respective insulative coatings.

Abstract
A multi-anodic aluminum electrolytic capacitor includes an electrical connection to the multiple porous (e.g., tunnel-etched) anodes in an anode stack using a single anode tab that is attached only to a first anode. Other anodes are electrically coupled to the anode tab through the first anode. Anodes in the anode stack are in intimate physical and electrical contact with other such anodes as a result of layering effected by planar stacking or cylindrical winding. The need for separate tabs to different anode layers is eliminated or at least minimized, thereby reducing capacitor volume, increasing capacitor reliability, and reducing the cost and complexity of the capacitor manufacturing process for multi-anodic capacitors. The capacitor is capable of use in implantable defibrillators, camera photoflashes, and other electric circuit applications.
